Developer Terms
Last updated: 6 November 2026
These terms apply when you submit a game to KoolGames, which is run by [Business name] (“we”, “us”). They sit alongside our Terms of Use, Community and Content Guidelines and Copyright and Takedown Policy. By ticking the box on the submission form, you agree to them.
What you promise
When you submit a game, you confirm that:
- you own the game, or you have permission from every rights holder to submit and distribute it, including its code, art, music, sound, fonts and any libraries it uses;
- the game doesn't infringe anyone else's rights, and doesn't break the law;
- the details you give us are accurate, and you will keep your contact email up to date.
Permission to host and promote your game
You give us a worldwide, non-exclusive, royalty-free licence, for as long as your game is on KoolGames, to host, copy, cache, stream and display your game, and to use its title, description, thumbnail, screenshots and preview video to list and promote it on KoolGames, in search results and on our social media. You keep all your other rights, and you can publish your game elsewhere. If you give us a link to a game on your own server, you give us permission to embed it, and you must keep it online and working.
Content rules
Your game must follow our Community and Content Guidelines. Games on KoolGames are for a teenage and adult audience. In particular, a game must not:
- contain real-money gambling, sexual content, or graphic violence;
- contain malware, hidden downloads, pop-ups, forced redirects or anything that tricks players;
- collect personal data from players, or set cookies, unless it tells them clearly, follows UK GDPR and the rules that apply to children's data, and gets consent where the law requires it;
- show its own ads, unless we have agreed that in writing.
Technically, your game must be HTML5, run inside a frame on a page that uses HTTPS, load quickly, and work in current versions of Chrome, Safari, Firefox and Edge.
How we review games
We review every game before it goes live. We may reject a game, ask you to change it, or remove it later if it doesn't meet these terms. We decide where games appear on the site, and we don't promise any number of players.
Revenue share
We show ads on your game's page. You'll receive: [Revenue share, for example 50% of net advertising revenue earned on your game's page]. We pay [payment schedule] once you have earned at least [minimum payout]. Payments are based on the ad revenue we actually receive for your game's page, less refunds and invalid traffic, and we'll send you a report with each payment. You are responsible for your own taxes. We may hold back or reverse payments if we find fraud or invalid traffic.
Removing a game
You can ask us to remove your game at any time by emailing [Contact email]. We'll take it down within [14 days]. We can remove or disable a game straight away if it breaks these terms, if we receive a valid copyright or other legal complaint, if it stops working, or if the law requires it. Revenue earned up to the day of removal is still payable. Copies stored by search engines or caches may take a little while to disappear.
Updates
To change your game, contact us with the new version. We review updates in the same way as new games.
Responsibility
If someone makes a claim against us because your game breaks their rights or these terms, you'll cover our reasonable costs and losses [confirm with your adviser]. Our responsibility to you is limited in the way set out in the Terms of Use, and we don't promise that your game will be accepted or earn any money.
Ending these terms
Either of us can end these terms at any time by removing the game as described above. The parts that need to carry on, such as payment for revenue already earned, carry on after that.
Changes and law
We may update these terms and will change the date at the top. If a change affects games already on the site, we'll email you. These terms are governed by the laws of [England and Wales].
